My favorite feature of this fan is that it runs from USB power and I can run it from an external battery which makes it totally portable. It also can work when the power is out. I live an area with a lot of trees and during storms we lose power at least a few times each year. When power is out the fans that can run on external batteries provide some much needed ventilation. The USB cord is 42" long.
The fan is small but generate a pretty good air flow for its size. The fan is quiet but not totally silent I can hear a slight hum of the motor. The sound it generate is white noise and is easy to ignore, so far it makes no no creaking or clanking sounds.
You can find it on Amazon by following this link.
